# A Podcastle alternative built for audio only

Podcastle is a suite: record, clone a voice, edit video, publish. Cast deliberately does less. It is for the show that ships as audio — edited by reading the transcript, scored with music generated for the episode, and exported at the loudness the platform expects.

## Podcastle vs Cast, at a glance

| | Podcastle | Cast |
|---|---|---|
| Scope | Recording, AI voices, video, publishing | One audio episode, finished properly |
| AI voices | A headline feature | None — your voice is the show |
| Video | Supported | Audio only, on purpose |
| Editing model | Text and timeline editing | Transcript first, with every cut listed and reversible |
| Music | Library tracks | Generated for this episode, ducks itself under the voice |
| Licence | Per their plan terms | Commercial licence and a per-export licence record (Plus/Max) |
| Loudness | Export settings | Platform presets — −14 / −16 / −23 with true-peak headroom |

## Breadth costs something

A suite that records, clones voices and edits video has to be adequate at all of it. The audio finish — the ducking curve, the true-peak headroom, the loudness target for the platform you actually publish on — is where that breadth usually shows.

Cast spends everything on that last mile instead. Music is generated per episode and sized to the segment, the ducking follows the clips rather than a rough level, and the export lands on the target because the target is a preset, not a plugin you have to understand.

- Audio only — no video, no AI voices
- Music generated per episode
- Ducking follows your edits
- Loudness by platform preset

## When Podcastle is the right call

If you need to record remote guests, ship a video version, or generate narration in a synthetic voice, Cast will not cover you and does not pretend to. Record there, finish here — or stay there, honestly, if the suite is what your workflow needs.

## FAQ

### How is the music generated for my episode?

Describe what you want, pick what kind of track it is — a background bed that loops, an intro/outro, or a short sting — and Cast generates an original track for the episode. It is generated for you, not pulled from a catalogue other shows are also using.

### How does the music duck under the voice?

That is auto-ducking. The music drops under the voice and comes back in the gaps, automatically — and because the duck follows your actual voice clips, it stays correct after you cut. Trim a minute of filler and the music re-balances itself. You never draw a volume envelope by hand. You can set how far it drops, or switch it off.

### Is the music licensed for commercial use?

Yes — music you generate in Cast comes with a commercial license on Plus and Max, and every export made on those plans carries its own license record. Free music is only free until a platform, a client or a rights holder asks where it came from; here you have a license record on file to show where the music came from. (Free and Lite have no commercial license, and music you upload yourself is yours to clear.)
